Please assume I'm aware of the GCS.

That section explicitly says these are recommendations, not hard
requirements, a little above the text that you cite:

     The rest of this section gives our recommendations for other aspects
  of C formatting style, which is also the default style of the 'indent'
  program in version 1.2 and newer.  It corresponds to the options

       -nbad -bap -nbc -bbo -bl -bli2 -bls -ncdb -nce -cp1 -cs -di2
       -ndj -nfc1 -nfca -hnl -i2 -ip5 -lp -pcs -psl -nsc -nsob

     We don't think of these recommendations as requirements, because it
  causes no problems for users if two different programs have different
  formatting styles.

So please do not push too hard for adopting only one style and nothing
else.  Doing so makes this community less pleasant than it should be.
